Better typing and type verification
...
- Extend verifier to check types of JS and Simplified nodes.
- Untyped nodes now contain NULL as types, enforcing hard failure.
- Typer immediately installs itself as a decorator; remove explicit decorator installation.
- Decorator eagerly types all nodes that have typed inputs
(subsumes typing of constant cache, removing its typing
side-channel and various spurious dependencies on the typer).
- Cut down typer interface to prevent inconsistently typed graphs.
- Remove verification from start, since it caused too much trouble
with semi-wellformed nodes.
- Fix a couple of bugs on the way that got uncovered.
To do: verifying machine operators. Also, various conditions in the
verifier are currently commented out, because they don't yet hold.

[turbofan] Fix lowering of typed loads/stores.
...
Only JSLoadProperty/JSStoreProperty nodes with external typed arrays can
be lowered to LoadElement/StoreElement, because lowering of non-external
typed arrays would require a map check.

[turbofan] Fix lowering of typed loads/stores.
...
We can only access to external typed arrays; lowering of internal
typed arrays would require a map check plus eager deoptimization.
Also embed the array buffer reference directly instead of embedding
the typed array.
